The object of this book is to provide a simple introduction to the Indian systems of philosophy. Each one of these systems has had a vast and varied development. Attempt has been made to introduce the reader to the spirit and outlook of Indian philosophy and help him to grasp thoroughly the central ideas rather than acquaint him with minute details. Modern students of philosophy feel many difficulties in understanding the Indian problems and theories. Their long experience with university students has helped the authors to realise these, and they have tried to remove them as far as possible. This accounts for most of the critical discussions which could otherwise have been dispensed with.

The book has been primarily written for beginners. The first chapter which contains the general principles and basic features of Indian philosophy, as well as a brief sketch of each system, gives the student a bird's-eye view of the entire field and prepares him for a more intensive study of the systems which are contained in the following chapters. It is hoped, therefore, that the book will suit the needs of university students at different stages, as well as of general readers interested in Indian Philosophy.
